1. A method of coating a coil, the method comprising:
- injecting a material comprising a first polymer and a gelling precursor into a container containing the coil;
gelling the gelling precursor to provide a first coating on the coil, the coating comprising the first polymer and the gelled precursor;
cross-linking the first polymer in the first coating to provide a second coating on the coil, the second coating comprising the cross-linked first polymer and the gelled precursor; and
removing the gelled precursor from the second coating to provide a third coating on the coil, the third coating comprising the cross-linked first polymer having pores therein.

Abstract
Coils, such as embolic coils, can include a substrate; and a porous material supported by the substrate. Related methods, devices, and compositions, can include: injecting a material into a container containing the coil; and forming the material into a coating that is supported by the coil and/or contacting the coil with a composition comprising a first polymer and a gelling precursor; and forming the composition into a coating that is supported by the coil.
